Title: Output circuit part of read only memory
Inventor: HIRASHITA TAKASHI
IPC: G11C29/00
Filed: 1984-06-15
Abstract: PURPOSE:To set output data in the desired bit state in a short time and to shorten the wafer test time by detecting contents of the control signal of a control terminal by means of a circuit part of an ROM, turning a switching circuit part on or off and providing a control circuit for outputted read data selectively from a buffer circuit. CONSTITUTION:Since control signals A and B are different in a wafer test mode, the output signal C of an exclusive NOR circuit 6 goes to zero level, and a switch circuit 3 is turned off. Then an output buffer circuit 1 is separated from a memory circuit. On the other hand, the signal D of an exclusive OR circuit 7 goes to ''1'' level, while transistors TrsT11, T12, T7 and T8 and turned on. Control signals are fed to an FF circuit 2 through buffer circuits 8 and 9, and the circuit 1 outputs ''1'' or ''0''. Since logic levels of the control signals A and B are equal in a memory action mode, the output signal of the circuit 7 goes to zero, and the circuit 1 is separated from control terminals 4 and 5. Meanwhile, the output signal C of the circuit 6 goes to ''1'', and the circuit 3 is turned on. Then, in correspondence to the read data from the memory circuit, the circuit 1 outputs ''1'' or ''0''.

Title: Gate turn off thyristor
Inventor: KOBAYASHI TAKASHI
IPC: H03K17/732
Filed: 1982-07-14
Abstract: PURPOSE:To turn on or off a gate easily and to form a gate driving circuit simply by connecting the 1st transistor(TR) with two TRs of which polarity is different from the 1st one by Darlington connection. CONSTITUTION:In the figure, Q1 and Q2 show pnp and npn TRs respectively. TRs Q2, Q3 constitute Darlington connection and the emitter of the TR Q3 is used as the cathode K of a gate turn off (GTO) thyristor. Consequently, negative gate bias voltage of the voltage between the gate and cathode of one npn TR is applied between the gate G and cathode K of the GTO thyristor and the input impedance of Darlington connection TR is increased higher than a single TR, so that the outflow of the current is easily performed, a base current component i2 is reduced and large capacity current is turned off easily. Since the current amplification factor of composite TRs at the time of Darlington connection is the product of both TRs Q2, Q3 as compared to the single TR Q2, the gate can be turned off with low gate current and the gate current can be reduced.

Title: Reference voltage circuit
Inventor: IKEDA KOICHI
IPC: G05F3/30
Filed: 1989-05-16
Abstract: PURPOSE:To eliminate necessity for separating an activating circuit for activation and to obtain a reference voltage circuit, which can easily stabilize circuit operation, by providing plural transistors, current mirror circuits, feedback circuit and constant current source for activation. CONSTITUTION:Transistors TR 18-24, for which prescribed connection is execut ed, equipped with prescribed characteristic, resistors 16, 17, 27 and 28, current mirror circuits (TR 18 and 19), feedback circuits (resistors 27 and 28) and con stant current source 25 are provided. Thus, when a voltage is applied between power supply terminals 1 and 2, the current source 25 supplies the base current of the TR 24 and this TR is set in a turning-ON state. Then, the collector currents of the TR 18 and 19 flow and the current mirror circuit is activated. The collector currents of the TR 20 and 21 are matched and a stable and exact band gap voltage is obtained in the both ends of the resistor 28. Then, a voltage amplified by a ratio between the resistors 27 and 28 is obtained in an output terminal 3. Since the current source defines the base current of the TR 24 and the emitter current of a TR 26 as a supplying circuit, necessity for separa tion is eliminated.

Filed: 1984-06-14
Abstract: PURPOSE:To obtain observable pictures reduced at their contrast variance in respective screens by adjusting a picture at its optimum state in each screen by a video adjusting circuit to display it. CONSTITUTION:A picture signal of a channel selected by a channel selection part 2 is extracted from a video detecting circuit 4 to a video switching circuit 11.

The adjusted signal is applied to an A/D converter 5 and digitized similarly to other picture to be reproduced on multi-screen. Since the once adjusted contents are stored in the circuit 14, pictures are reproduced in the same adjusting state until the adjusting state is changed.

Title: Gear clutch device of copying machine or the like
Inventor: KOBAYASHI HIROO
IPC: B41J11/00
Filed: 1981-08-08
Abstract: PURPOSE:To ensure stable gear engagement, by forming inclined parts on the tooth faces, not coming into mutual contact, of the addendums of both gears. CONSTITUTION:An interlocking gear 24 appears to fit into a driven gear 10 to be engaged soon from a position shown by the dotted line, but it does not actually fit into the recess as shown by the full line, and touches the addendum of the gear 10, so perfect engagement is not attained. Since the gear 10 is in a smooth fitting state to a driven shaft, it rotates passively in synchronism to the gear 24, and instantaneous engagement is not attained. In order to prevent this phenomenon, the tooth faces of the addendums of the 2 gears not coming into contact to each other are beveled to form inclined parts and to decrease the collision zone. Since the outside of Z, the locus of the engaging point of each gear is the regions 102 and 242 not contributing to the engagement, these parts are subjected to beveling 101, 241, thus permitting regular engagement to be attained without impairing strength, and the gear to fit into the recess of the other gear.
